Filed: 1925-11-17
Abstract: 266,052. Dawson, Sir A. T., and Buckham, Sir G. T. Nov. 17, 1925, Endless-track vehicles.-In motor vehicles of the kind having endless-tracks and road wheels for alternative use. the engine drives the road wheels, when required, through differential gear D<3>, Fig. 3, the planet carrier of which can drive the endless-track sprockets C<1> through friction clutches F, steering being effected by disconnecting the appropriate clutch and applying a brake F<3> thereto. The differential gear drives the road wheels through jack shafts b<x>, clutches B‹, and chain gear b‹. The clutches 6‹ are controlled by levers B<2>. rods B<3>, and rollers b<3>, the latter being acted upon by cams B<4> on the chassis frame, so that as the vehicle is converted from the wheeled to the endless-track state the clutches are automatically disengaged, and vice versa. The friction clutches F drive the track sprockets through sleeves F<1> on the shafts b<x>, and are disengaged when required by means of rods f<2>, each operated by a hand lever which also controls the corresponding steering brake F<3>. In the modification shown in Fig. 4 the tracks are driven through epicyclic clutches, the differential planet carrier D<3> being rigidly connected to internally-toothed rings d' meshing with planet pinions d<4> rotating on planet carriers D' carried by the sleeves F<1> driving the track sprockets. The planet pinions gear with sun wheels D<5> which can be held fast by brakes D<5x>; when this is done the track sprockets are driven through the epicyclic gears. Steering is effected as in the first construction by releasing one clutch and apply a brake to the corresponding track sprocket. In both constructions, independent brakes may be provided for normal braking. In order to prevent the tracks '' creeping " when not in use brakes are automatically applied thereto as the vehicle is converted to the wheeled state, the means employed being those forming the subject-matter of Specification 266,393. The invention is shown applied to a vehicle of one of the constructions described in Specification 265,688.

Title: Improvements in a process and apparatus for the manufacture of carbon black
IPC: C09C1/50
Filed: 1952-11-17
Abstract: <PICT:0716849/III/1> <PICT:0716849/III/2> In producing carbon black by the injection of hydrocarbons into a turbulent stream of hot blast flame gases passing through an elongated reaction chamber, the said gases are supplied to the reaction chamber as separate highly turbulent streams converging towards one another at 60-120 degrees and toward the upstream extention of the reaction chamber at 30-60 degrees, preferably symmetrically; hydrocarbons are injected into the so-formed zone of impact and the mixture passed in a state of violent turbulence through the reaction chamber.  An apparatus having the preferred features is shown in horizontal cross-section in Fig. 4. The reaction chamber 1 is lined with heat insulating material 2 and is of rectangular cross-section, having the height greater than the width.  The combustion chambers 5 (of which there may alternatively be more than one pair oppositely positioned and uniformly spread over the height of the reaction chamber) are of similar construction and equipped with the type of blast burners described in Specification 654,340; they should together be of transverse area at least equal to the maximum transverse area of the reaction chamber, but may greatly exceed it.  Liquid make hydrocarbons, to which the invention specially applies are introduced as finely divided sprays through any or all of nozzles 15, preferably constructed as described in Specifications 692,129 or 692,130, and meet the blast flame gases at about 2-3000 DEG F.  It is found particularly advantageous to use the opposing vertical burners only to avoid contact of injected hydrocarbons with the opposite wall.  The cross-section of the reaction chamber may be uniform but is preferably reduced as described in Specification 715,713 downstream of the confluence of the combustion gas streams.  The combustion chambers may also be tapered toward the zone of impact if desired.  Carbons of suitable adjustment of operating conditions: examples are given.  U.S.A. Specification 2,378,055 also is referred to.

Abstract: 1,195,844. Programmed control. D.A. LEADBEATER. June 30, 1967 [July 1, 1966], No.29553/66. Heading G3N. In a control apparatus a plurality of switching devices are actuated in a fixed sequence to actuate a plurality of controlled devices in a sequence variably related to the first sequence by a switching device comprising a series combination of a relay switch matrix and a membrane controlled switching device. As shown, Fig. 1 a scanning device A sequences a supply to terminals A1-A5 which are connected to a relay switch matrix M variably transposing their inter -connection to terminals I-IV under the control of input voltages A-C. The outputs on terminals I-IV are applied through switches VI-V8 to apparatus-controlling lines W-Z. The status of switches VI-V8 is determined by a control member D, pierced with a pattern of apertures H. The apertures are aligned with pins E coupled to the switches and the absence of an aperture closes a switch to connect the appropriate line W-Z. The scanning device A comprises a relay ring stepped by a change-over relay responsive to a switch controlled by the completion of an operation. The relay switch matrix M comprises a switch contact tree wherein contacts of relays forming the relay ring are selectively interconnected by contacts of relays energized by input voltages A-C. The lines WZ are connected to control operations of a machine tool. The control line X, Fig. 4, energizes an electro-magnet XCM controlling a clutch coupling a motor to drive a worktable WT in the X direction and energizes a relay XC/1 controlling a brake. The actuation of a limit switch LS closes an operating circuit for a relay L/1 having a switch contact which steps the relay ring through the change-over relay. Similar arrangements are provided for the Y and Z coordinates and further limit switches are arranged to energize the relay L/1.

Title: Improvements relating to sheet feeding apparatus for printing machines
IPC: B41F33/06
Filed: 1925-11-25
Abstract: 268,405. Crabtree & Sons, Ltd., R. W., and Hawkins, G. Nov. 25, 1925. Tripping-arrangements. - A rotary printing- machine which is provided with means such as are described in Specification 179,637 for tripping the cylinders of the printing-couple and simultaneously moving the front stops o and sheettaking grippers to inoperative positions, so that when the printing-couple is tripped the sheet is not fed past the front stops o, is provided with an automatic or semi-automatic sheet-feed consisting of rising and falling runners l coacting with a driven bottom roller m, and the tripping- mechanism for the printing-couple causes the runners l to be held in their raised position shown, so that the sheet held by the stops o is not over-run by a second sheet when the printing- mechanism is checked. The runners l cooperate with sheet-stops b which are normally raised as the runners fall. The runners l may be held in their raised position by a catch d' associated with a rod z which controls the tripping motion of the press. The rod z and catch d<1> are connected by a bell-crank y and spring c<1>. The rod z may be hand-operated, but as shown is controlled by a feeler p near the front stops o and is arranged to trip the press if the sheet is not fed correctly. If the sheet is fed correctly it releases the feeler n from a bar u and permits motion of a lever-arm r on a shaft v connected by a lever w, rod x, bell-crank y to the rod z which can follow a cam b<1> and thus falls when the cam permits. As it falls it releases the catch d<1> and also moves a shoe z<3> on an oscillating lever z<4> out of the path of a rod z<6> connected to the tripping-mechanism of the press. If a sheet fails to act on the feeler p, the rod z is maintained in the position shown, and the rod z<6> is operated to trip the printing- mechanism. The catch d<1> also maintains the runners l in the raised position.
